PROBLEM TO BE SOLVED: To provide a method for automatically washing a filtering apparatus of a water-sprinkling type manuring device which uses a pollutant-containing water source, with respect to water-sprinkling type manuring cultivation of crops including flower vegetables and flowering plants.SOLUTION: This method for washing the filtering apparatus comprises discharging and washing pollutants in the filtering apparatus, in the water-sprinkling type manuring device installed with the filtering apparatus which removes foreign substances from natural water. In more details, the method comprises opening a drain solenoid valve of a drainage pipe of the filtering apparatus and closing a solenoid valve of a water-sprinkling and manuring tube, and opening a raw water solenoid valve of an intake source or operating a watering pump, or alternatively, stopping the watering pump of the intake source or closing the raw water solenoid valve, and closing the solenoid valve of the water-sprinkling and manuring tube, and opening the drain solenoid valve of the drainage pipe of the filtering apparatus.COPYRIGHT: (C)2009,JPO&INPIT【課題】果菜類及び花き類を含む作物の潅水施肥栽培に関し、汚濁物を含む水源を使用する潅水施肥装置の濾過装置を自動洗浄する。【解決手段】原水の異物を除去する濾過装置を介設した潅水施肥装置において、前記濾過装置内の汚濁物排出洗浄を、濾過装置のドレン排出パイプのドレン電磁弁を開とし潅水施肥するチューブの電磁弁を閉止し、取水源の原水電磁弁を開にしまたは潅水ポンプを稼動させて行うか、又は取水源の潅水ポンプを停止又は原水電磁弁を閉とし、潅水施肥するチューブの電磁弁を閉とし、濾過装置のドレン排出パイプのドレン電磁弁を開として行うことを特徴とする潅水施肥装置の濾過装置洗浄方法。【選択図】 図1
